If Robotroll had actually watched that video, he'd known that Linus got burn in on the OLED tv he used as a monitor for his Windows PC. He said the OLED TV he used for its intended purpose (tv/gaming) had no burn in.
Unless you keep you tv on as a monitor 24/7 you can use it as a monitor.
I'm literally writing this post using my oled as a monitor.
The ONLY thing i had to do as a precaution was to hide the bar on the bottom when i'm not using it, i can't even call that a compromise or sacrifice.
Then i pretty much do the fuck i want with the tv, i watch 90 min anime movies with sport\vivid mode because i like popping colors in my weeb content, i browse with chrome for hours when i have nothing to do, i watch\play hdr content, i play long 3-5 session of games with fixed icons, like i was at home in the past 2 weeks because i had a small surgery and i played like 100 hours of mhw on pc, ask me if i have even the smallest sign of burn in, i dare you.
If i have to point out something is that since i like color accuracy i watch\play most of my stuff in professional mode (filmmaker on lg tv, mine is a panasonic), and for some people, color accuracy mode is a bit mute, but it's not a sacrifice for me, and i still use game mode for something cartoony like zelda botw (played 5-6 hours of it in the last 2 days without a problem).
But watching anything that is not anime\sport in vivid mode is fucking puke inducing, so it's really not a big sacrifice, i think majority of people use movie\game mode as the most common modes anyway.
p.s. oh and i had this type of usage since my first oled tv, an old lg 910V full-hd, so it's not even a matter of having a modern oled.
